Hello Markus,

I just configured SL = to=20 transmit OP32. Works well it seems.
However, if i try to use a=20 macro:

the=20 last signs, 00000000", are ignored by SL. Probably a limitation of = characters in=20 one row of the scheduled actions?

I'm just trying = that. If i=20 remove the last 0 and replace it by ", SpecLab accepts the row and = transmits the=20 sequence from the scheduled actions...

This was a local test. I'm going to test your RX accuracy now=20 :-)
